I want to make a slipjoint so bad. Its driving me crazy I have read some links
my questions are

1. I don't like bolsters can I make a sj without will I get enough tension on the blade but not crack the handle?

2. If I were to build a sodbuster style is the pivot pin a cutlery rivit would that work?

3. I thought about getting a kit mainly for a pattern and put them together side by side so I will have one that I know is right to judge the other one by do ya'll think that would be best?

4. I have never soldered if I do use bolsters do have to solder?

5. And is there anyone close that would be willing to help?

Any info would be greatly appreciated
thanks

1. you can but I think you realy need a bigger pin if you do.
2. what kind of use?
3. having a patern is a good idea, took me about 4 tries to make one with out a pattern, not as easy as it looks
4. you dont have to solder if your not going to have bolseters, go to the makers for sale sect and look at Ken Coats texas tooth picks great example, ther are others such as sodbusters as well that dont have bolsters

great thread, ive started 3 or 4 and they made the junk drawer long before coming even close to making it on a table or in some one's pocket.

got one in the works now, that has potential, but prob. will just be for me.

Dont feel bad I have a coffee can full of slipjoints that I had started and some how didnt get right(and a couple that worked but didnt have the right look to them). Before some help from some of the fourm members, I couldnt get one to work, but now that I have figured out some of the tricks It is much easier.
 
I have made a bunch and do it without a mill and extra machinery, I will be willing to share what I have learned with you. I am no expert just alot of practical experience. My first suggestion is make a plastic knife. Plastic is great because you can make a complete knife and the spring will actually work. this allows you to work out design problems before you cut steel.

I have a pattern for a coke bottle (swell center) that Kerry Hampton posted over a year ago, I believe the orginal pattern came from Tony Bose. I will try to find their original post if you would like a nice pattern. I followed it and it made a really great knife.

here is a link to the orginal post showing the pattern, I used the pattern to make a plastic model and then the plastic to mark my steel. I would like to make another, i lost the one I made if you want to work together.

i think a kinda slip joint 101 thread would be cool, like maybe some one hear that has "mastered" them, or has a good knowledge of how they are built correctly, could step up to the plat and kinda play teacher.

my idea would be kinda like: give us a materials list, then maybe a step by step process, like a homework assignment.( each new post being another step to complete) each of us showing our progress as we go along. maybe it's a corny idea, but i think it'd be fun.

iv'e read a few tutorials on slips, but it's easier to do if your working with someone , even if not in person.(then i couldn't just keep putting them off)

any takers????

personally, i'd rather build a traditional slip joint (single blade) rather than one of these new high tech screwed together jobs.

My goal is to get where I can make a presentable slipjoint, but looking at the complexity, I am still trying to make simple paring knives. These are some links that I have gathered that might help.

Chris Crawford - How to make a slip joint pocket knife

Bose Backpocket Knife Construction This is Liner/Bolster Buildup, Final Assembly and Finishing by Tony Bose

Also - Project 8 in "Custom Knifemaking - 10 Projects from a Master Craftsman" has good details. It's from a metalsmith/jewelry guy, but I think its still valid.

I'll be checking this thread to see everybody's input.

Thanks

Well, it was just brought to my attention that I highjacked this post. If thats what it was perceived as then I'm sorry. Won't happen again! I'm just trying to help! I thought by doing a contest it would make things interesting. Its not meant to be a marketing ploy. I pay for this out of my pocket to help makers learn to make a knife. I don't sell "KITS"! :mad: If it was a kit then everyone's knives would be the same. I've been very fortunate to be a part of these forums and enjoy seeing the growth of knifemakers. I will continue to assist anyone as best I can. Once again, sorry for the "jack".
 
Starting with some precut parts is not a bad place to begin. If you wish I will help you cut your own parts from your pattern or the coke bottle and also advise others on how to assemble and get the spring tension correct once they get their parts, how to mount bolsters and fit handle material. In the long run you will learn to make a slip joint.

The methods are pretty much the same no matter what the pattern.

I think we can all work together on this and maybe get some makers that have more experience than me to help.

What do you think???
 
I wouldn't consider bringing an existing thread to peoples attention a "jack". I am also sure you had no greedy intentions. You have been generous and helpful on this forum. Removing the link just goes to show what a nice guy you are.

Thanks rick, let see what people want to do, I have a couple of patterns. Some may want to go the precut route for a starter and others may want to start from scratch. I would very much like to work with you, I am sure there is alot I can learn.
 
Paterns on paper are a good guide to go by but I like to have a Master patern (a blade/spring that are close to finished) that I know works. just to trace off on to the stock Im using.
 
I do the same, I make a paper pattern, transfer to plastic model and then I will mark at least 3 metal sets of parts. I hope to have one knife and one set of patterns when I do the first. I then use the metal pattern after that. I usually have trouble with the spring so I have an extra spring and hopefully do not have to make another once I get started. A metal pattern for the spring is really helpfull so I can hold the two together to make sure everything is good to go.
