Re: Sincliar case trimmer

Being a machinist at heart and appreciating a radical departure from the norm, I just ordered one of Little Crow Gunworks WFT-2 ttrimmers. It's like the Giraud but powered with either a drill motor or in my case, a lathe with a collet.

Same basic design as the Giraud where the case indexes on the shoulder and the shoulder determines the cut length but unlike the Giraud, the WFT-2 has interchangaeable chamber reamed inserts for almost any bottleneck cartridge ( or you can ream your own as Little Crow supplied sized blanks if you want to machine an odd cartridge size) whereas the the Giraud is a production machine and changeout entails changing the entire cutting unit.

There is no pilot whatsoever as with most spindle type cutters and the case remains stationary while the entire head and HSS cutter revolves. Note I said HSS, not Tin coated Tungsten Carbide as with most trimmers plus the Little Crow outside chamfers and inside chamfers the case in the trim operation. I'll still VLD ther inside chamfer. I'm sold on the low drag insertion, especially for flat base projectiles.

They are special, made to order. When it comes, I'll have to do a review for the forum.

According to the information I've been able to obtain, 0.0005 (5 tenths) variation between cartridge length is the norm. Way better than the Redding does without careful manipulation and it's easily capable of 20 cases per minute (according to the website). Cutter life is claimed at 5,000 cases and the cutter is an off the sheldf end mill.

Little Crow also makes a dedicated, one caliber trimmer, the WFT, but I can't see only having the capability of trimming one caliber.

Cost is very commensurate with the Redding micrometer head trimmer
