Sinclair Comp Rest Windage Preloader

If I told you I understood the logic completely, I'd be lying. But, if folks want to buy twice as many, I'm totally on board with that ;)

Seriously, though...

I developed these for the LR benchrest crowd. They were the guys that I witnessed "taking matters into their own hands" already. They want everything to stay put throughout a string unless they dial some adjustment, which is usually very small. But once dialed, the rest needs to respond without any backlash, then stay put again. Therefore, when testing, I installed it to work in conjunction with the factory spring - how I envisioned 99% of customers using them. It does a great job to this end, although it makes the knob a little stiffer to turn. If I remove the factory spring and plunger altogether, I still have a lot more spring pressure than factory and the rest seems to still perform very well. This lightens the input effort required on the knob somewhat. Since the majority of our hillbilly benchrest is discrete targets at 300-550yds with heavy rifles, I suspect this is how I'll use mine long term. If I'm running groups during load work or on a good condition Fly Shoot Day (ha, ha, ha), I'll probably go full monty on the spring tension.

I think the gentleman interested in running two opposing one another is a short range BR shooter. Something that I haven't done much of, and will likely use a joystick top when I do going forward. I think his concerns are more geared towards responsiveness and being able to traverse targets quickly with rifles 13.5# and under. Again, this is purely speculation on my part. I'm certainly not going to doubt him, as he seems very well versed in his game. I just hope he's still interested once he sees the production units are still "over built", which was his major recommendation.

If they are over built, maybe they need to be fluted!! Lol!

SIGH>>>>> I shot 1K competitively for 6 years and did very well. The first year was a learning experience looking over everyones equipment and seeing what worked. $$$$$$$.

After a few year hiatus I feel like I need to go to some matches just to watch and see what everyone is shooting on and with!! Things are changing rapidly.

My BAT's are out of style.
My Dasher is going out of style.
My ST1000 is out of style.
My 1010 scale is out of style.
My old rockchucker is old.
My front Hart rest is out of vogue.
My rear bag is out of style.
My RL15 is out of vogue.
My berger bullets are out of date.
My Jewell is out of date.

At least i still have my 450's....for now!!

I think your list is fine, but check your scopes. That seems to be one of the most important developments over the last few years in LR Benchrest.
 
Yes a lot of guys have rigged up springs to keep the tension. These are a good idea. I remember talking with one of our shooters that used to shoot deep creek about his rest moving when firing. He had high speed camera for explosives work. His rest had strong springs...
 
Yes! Material is here, work order is in the shop.

Based on field testing, I made the following tweaks to the production units vs. what is pictured:
  • Switched to a nylon acorn nut to protect the aluminum Sinclair post carrier
  • Changed the mounting to one tapped thru hole and one hole that's counterbored on both sides to accept a lock nut and washer. Of the 6-ish folks that have tried it, one had a hole pattern about .02" different in his Sinclair base. The new design is more forgiving on the hole locations.
  • Changed a counterbore depth to give it a little more travel. It is now capable of +/- .33" from center (based on my rest)
  • Pricing will be $75 for one delivered within the US or $130 for a pair delivered. At least one tester wants them on both sides.
It should be 2-3 weeks before the listing is live.

Thanks!

i would like to buy 2
