Turret drill jig

[Steve Stafford (JBEES)]

I have come across a jig for drilling turret frames. It creates a hole to position the indexing stop latch in a way to prevent multiple indexing and prevent fail to indexes. Has anyone seen these and how well do they work...has anybody tried them? What did you think of it? Just looking for some remarks.

Re: Turret drill jig

What you probably are talking about is a jig that allows you to drill a hole and install a rollpin next to the turret latch.By doing so it makes your peddle adjustment less critical and stops all turret indexing problems(LOL).Like so many other tricks,how good it is depends on who you talk to.I personnally don't like it.It does remove some peddle adjustment error and thats fine but its will not correct all indexing problems.I don't know of it ever doing any harm so if you wanted to try it go for it.I never felt it was worth the time.Hope that helps.

This is my second center with that modification installed, I think David is correct I havent seen it cause any problems and it does make the indexing trip lever adjustment less critical, but it will not stop all of your indexing problems, although I think it does seem to help. I would reccomend installing it if you have the jig to do it with. I have noticed it provides a more positive stop for the indexing latch in its rearward motion. That modification along with the kit from Quality to replace the x-pins in the short link with bolts will help your linkage tremendously.

just my inexperienced 2cents worth

Re: Turret drill jig

I was told I could remove the indexing trip lever stop. I would say that makes the pedal adjustment non existent...has anybody removed the stop?

Over the years different Places iveworked in had the stops removed and i never saw any problems that im aware of because they wasntthere.

Re: Turret drill jig

the roll pin upgrade is designed to eliminate the rear peddle adjustment not to cure any indexing problems. you do need to keep you're linkage in good condition or the upgrade is pointless. don't worry it'll let you know if your linkage isn't in good shape lol.i did it to all 24 of my machines and haven't had a problem since....good luck to you...shame

<font size="2" face="Verdana, Arial">Steve,
I have seen the original Brunswick Jig many years ago (my mentor had one) and we drilled all 40 of our turret frames and instaled the roll pins and removed the rear adjusting nut on the trip lever stud and never had any problems in the 5 years that I was at the center after that.

That was before Quality came out with the bolt and stud for the short link, but with a new short link, X-pins and the "Turret Indexing Retrofit",, we ran nearly 2 yeaars on A2's at A2 speed (these were new machines back then, straight from Muskeegan) with absolutly no turret problems at all regaurding indexing, until the x-pins and short links started to waer out.

I have one that someone on this site had made at a machine shop to match the one they had. I have never used it but plan on it one day when things actually slow down if that is possible.

Drill:
What is the center to center distance between the holding bolt hole and the drilling hole on the one you had made. Thanks in advance.

Hi Steve I have the jig you are talking about at this time my district f/m is using it in grandrapids michigan im planning on making a copy for him after I get it back if you want one just e-mail me .

jim at amf00542

O ya it wont fix any problems like bad xwasher pins on indexing latch or turret bellcrank wore out but if they are ok it will make the indexing padel more easy to be depressed by a pins weight on it .

thanks
